If you are using iijPPP, I would make sure and get the patches Doug
Rabson just committed to the -stable tree as they greatly enhance the b
robustness of it.

Sure, but the other machines on the same network don't have a route to
the box.

Not using iijppp.  You may want to get my 'ddial' patches to iijppp,
which cause it to always keep the link up, but they *require* the
stability patches above because it triggers some of the bugs it fixes.

iijPPP auto-configures tun0, so there isn't a need to do that.

You don't.

Because you're relying on your remote boxes to setup the addressing.
